This surgery involves making a small opening in your back to reach and remove kidney stones. Researchers are comparing a vacuum-assisted sheath (a device that helps with suction and irrigation during surgery) to a conventional sheath (a standard device for stone removal). Both methods are already used and considered safe and effective for kidney stones. The study aims to see how well each method clears stones (stone-free rate) and to look at surgical details and recovery. Approximately 90 people will participate. You may be eligible if you are 18 or older, have a kidney stone between 10-25 mm, and are planning to have a mini-PCNL.","Participants will be followed for approximately 4-6 weeks after surgery for a follow-up appointment with the surgeon.",123,"You would undergo the mini-PCNL surgery and have follow-up appointments for about 4-6 weeks after the procedure.","Not stated in the trial record.",[],"v2"]
